Cajun Oven Baked Shrimp Boil

I didn’t try a real shrimp boil until I was in my twenties, and honestly, I thought it looked like way too much work. All that outdoor setup, the massive pot, the propane burner—it seemed like something you’d need a backyard party to justify.

Then I realized you can get those same flavors by just tossing everything on a sheet pan and letting your oven do the work. No special equipment needed. No standing over a giant pot of boiling water. Just shrimp, sausage, corn, and potatoes with some good seasoning, and you’ve got dinner ready in about thirty minutes. It’s one of those meals that feels like you put in way more effort than you actually did.

Why You’ll Love This Shrimp Boil

  • One-pan dinner – Everything bakes together on a single sheet pan, which means minimal cleanup and more time to relax after dinner.
  • Quick and easy – This recipe comes together in under an hour, making it perfect for busy weeknights when you want something special without the fuss.
  • Restaurant-quality flavor at home – The combination of shrimp, sausage, and creole seasoning gives you that classic Louisiana taste without needing a giant pot or outdoor setup.
  • Complete meal in one dish – With protein, veggies, and potatoes all included, you don’t need to worry about making side dishes.
  • Great for entertaining – This looks impressive when you bring it to the table, but it’s actually simple enough to make any night of the week.

What Kind of Shrimp Should I Use?

For this oven baked shrimp boil, you’ll want to use large or jumbo shrimp (around 16-20 count per pound) so they don’t overcook and turn rubbery in the oven. You can grab either fresh or frozen shrimp – just make sure frozen shrimp are fully thawed and patted dry before tossing them with the other ingredients. I recommend buying shrimp that’s already peeled and deveined to save yourself some prep time, though leaving the tails on can make for a prettier presentation if you’re serving guests. If you can only find smaller shrimp at your store, just keep an eye on them and reduce the cooking time by a few minutes so they stay tender and juicy.

Options for Substitutions

This recipe is pretty forgiving, so feel free to make these swaps based on what you have:

  • Andouille sausage: If you can’t find andouille, kielbasa or smoked sausage work great. You can also use chorizo for a different spice profile, though it will change the flavor a bit.
  • Shrimp: Fresh or frozen shrimp both work fine. If using frozen, just thaw them completely and pat dry before cooking. You can also substitute with crawfish tails if you’re feeling fancy.
  • Creole seasoning: Don’t have creole seasoning? Make your own by mixing paprika, garlic powder, onion powder, cayenne, oregano, and thyme. Old Bay seasoning also works in a pinch and gives a similar coastal flavor.
  • Potatoes: Red potatoes, Yukon golds, or even baby potatoes all work well. Just keep the pieces similar in size so everything cooks evenly.
  • Fresh corn: Frozen corn on the cob works if fresh isn’t available. You can also use mini corn cobs, which actually look pretty cute on the plate.
  • Parsley: Fresh parsley adds a nice pop of color, but you can use cilantro or green onions instead if that’s what you have on hand.

Watch Out for These Mistakes While Baking

The biggest mistake with oven baked shrimp boil is adding the shrimp too early, which leads to rubbery, overcooked shrimp – always wait until the potatoes are nearly tender before tossing them in, since shrimp only needs about 10 minutes to cook through.

Another common error is cutting your potatoes too large, which means they won’t cook in the same time as everything else – aim for 1-inch cubes so they’re fork-tender by the time the shrimp is done.

Don’t forget to spread everything in a single layer on your pan, because overcrowding creates steam instead of that nice roasted texture you want, and if your pan looks too full, use two pans instead.

Finally, make sure your shrimp are completely thawed and patted dry before adding them to the pan, as excess moisture will prevent proper browning and dilute your seasoning.

What to Serve With Shrimp Boil?

Since shrimp boil is already packed with potatoes, corn, and sausage, you really just need some good bread to soak up all those amazing juices. A crusty French baguette or some warm dinner rolls work perfectly for mopping up the seasoned butter at the bottom of your plate. If you want to add a fresh element, a simple coleslaw with a tangy vinegar dressing cuts through the richness nicely and adds a cool crunch. You could also set out some extra melted butter mixed with lemon juice and garlic for dipping, or keep it simple with lemon wedges and hot sauce on the side for anyone who wants an extra kick.

Storage Instructions

Store: Keep your leftover shrimp boil in an airtight container in the fridge for up to 3 days. The shrimp stays pretty good, though it’s always best enjoyed fresh since seafood can get a bit rubbery when reheated.

Freeze: I don’t recommend freezing this one since the shrimp and potatoes don’t hold up well in the freezer. The texture gets pretty mushy and disappointing after thawing, so it’s better to just make what you’ll eat within a few days.

Reheat: Warm it up in the oven at 350°F for about 10-15 minutes, or until heated through. You can also use the microwave on medium power, but keep an eye on it so the shrimp doesn’t overcook and get tough.

  • Calories: 1550-1750
  • Protein: 100-115 g
  • Fat: 55-65 g
  • Carbohydrates: 140-155 g

Ingredients

For the bake:

  • 1.25 lbs shrimp (peeled and deveined, tail-on for better presentation)
  • 13 oz andouille sausage (sliced into 1-inch rounds)
  • 1 lb potatoes (I use Yukon Gold, cut into 1-inch chunks)
  • 3 ears corn (husks removed and cut into 3-inch pieces)
  • 4 garlic cloves (freshly minced for best flavor)
  • 1.5 tbsp creole seasoning (I prefer Tony Chachere’s for authentic spice)
  • 2 tbsp unsalted butter (melted)
  • 1 tsp lemon juice

For the garnish:

  • fresh parsley

Step 1: Prepare Ingredients and Preheat Oven

  • 1 lb potatoes, cut into 1-inch chunks
  • 13 oz andouille sausage, sliced into 1-inch rounds
  • 3 ears corn, cut into 3-inch pieces
  • 4 garlic cloves, freshly minced

Preheat your oven to 400°F.

While it heats, prepare all your ingredients: cut potatoes into 1-inch chunks, slice sausage into 1-inch rounds, cut corn into 3-inch pieces, and mince garlic.

Having everything prepped before you start cooking ensures the dish comes together smoothly without scrambling mid-recipe.

Lightly grease a large baking sheet or roasting pan (at least 9×13 inches or similar size).

Step 2: Build the Base with Potatoes and Sausage

  • 1 lb potatoes from Step 1
  • 13 oz andouille sausage from Step 1
  • 0.75 tbsp creole seasoning

Spread the cut potatoes and sausage across your prepared baking sheet.

Sprinkle with 3/4 tablespoon of the creole seasoning and toss to coat evenly.

The potatoes need the most time to cook through, so they go in first.

The sausage will add flavor to the vegetables as everything roasts together.

Step 3: Roast Potatoes and Sausage

  • potato and sausage mixture from Step 2
  • 2 tbsp unsalted butter
  • 1 tsp lemon juice

Bake the potato and sausage mixture for 20 minutes.

This gets the potatoes partially cooked and caramelized.

While this is roasting, I like to melt the butter and stir in the lemon juice—it takes just a minute and ensures the flavors are ready to go when you need them.

Step 4: Add Corn and Continue Roasting

  • potato, sausage mixture from Step 2
  • 3 ears corn from Step 1, cut into pieces

Remove the pan from the oven, add the corn pieces to the existing mixture, and toss gently to distribute.

Return to the oven and bake for another 5 minutes.

The corn only needs brief cooking, so it goes in just before the shrimp to keep it from becoming overcooked and mushy.

Step 5: Add Shrimp and Finish Cooking

  • roasted vegetables and sausage from Step 4
  • 1.25 lbs shrimp, peeled and deveined
  • 4 garlic cloves, minced from Step 1
  • melted butter and lemon mixture from Step 3
  • 0.75 tbsp creole seasoning

Remove the pan from the oven and add the shrimp and minced garlic.

Drizzle with the melted butter and lemon juice mixture from Step 3, then sprinkle with the remaining 0.75 tablespoon of creole seasoning.

Toss everything together gently to coat.

Return to the oven and bake for 10-12 minutes until the shrimp turns pink and opaque—don’t overcook or they’ll become tough.

Step 6: Plate and Garnish

  • cooked shrimp boil from Step 5
  • fresh parsley

Remove the pan from the oven and give everything a final gentle stir.

Divide the shrimp boil among serving bowls or plates, making sure each portion has shrimp, sausage, potatoes, and corn.

Garnish generously with fresh parsley for color and a fresh flavor boost.
